  • Devices used in lighting control systems eg central control devices, LED drivers, etc. are not compatible when the communication protocols are different.
  • the lighting control system is often applied to a large place such as an exterior wall of a building, a street lamp, or a lighting of a performance hall. Replacing lighting modules of one-way protocol with lighting modules of two-way protocol can be expensive. Therefore, there is a need for a lighting system that can gradually replace the lighting module of the new model.

That is, since a signal is transmitted to 511 channels, a specific channel can receive a control signal, which makes it difficult to control the real-time lighting.

Since it is not necessary to replace the lighting module with the one-way communication protocol with the lighting module with the two-way communication protocol, the model replacement cost can be reduced, and the existing lighting module can be used as it is, thereby reducing the installation cost. In addition, it is possible to automatically determine which LED module is abnormal, which can help equipment maintenance. By using a comparator without using an analog-to-digital converter (ADC), voltage and current measurements for determining the abnormality of the LED module are possible with a simple structure and low cost. After the lighting control data is first transmitted, the lighting modules may be controlled to correspond to the lighting control data when necessary, so that the lighting control may be performed in real time.
